Question

Arrange the following steps in the proper order to explain the How a sea breeze occurs near coastal regions.
(a) The temperature of land rises as a compound of sea, because the specific heat capacity of land is five times less than that of water.
(b) Due to low pressure over the landmass of sea, the cool air over the sea starts blowing towards the land.
(c)The sun shines equally on the land mass and light, rises up and hence creates the low pressure over the land.
(d) The air above the land becomes hot and light. It rises up and hence creates the low pressure over the land.

A) a d c b
B) c d a b
C) c a b d
D) c a d b

Answer 1

Hint: To solve this question, we should try to understand the entire phenomena of sea breeze. We should first start with how the process initiates, which phenomena causes its initiation, what are the things involved in the process and how it impacts the surrounding. We have to understand what comes next after each step.

Complete step by step answer:
We all know that sea breeze occurs during days because of the unequal heating rates of the land and water. It occurs during the day because the land surface heats up faster than the water surface. This heating of land also heats the air above it. The air above land becomes warmer than the air above the ocean. This warmer air is lighter than the cooler air. Thus, this warm air rises up. As the air over the ocean is relatively cooler and heavier, it flows down to take the place of the warmer air.

So we can conclude that the correct option is (D), c a d b.

Additional Information:
In the coastal Regions, when the sun shines equally on the land and the sea, both the land and sea receive an equal amount of heat energy. But the temperature of land rises rapidly as compared to the sea water because of its heat capacity which is five times greater than that of land. So, water requires more heat energy to raise its temperature by $1^\circ $ as compared to the land.

Note: The sea has a greater heat capacity than the land. Due to this, the sea can absorb more heat than the land without increasing its temperature. This is why the surface of the sea warms slowly as compared to that of land. The heated land heats up the air above it and hence causes a temperature gradient between air above land and air above sea.
